Title: Manufacture of semiconductor chip
Inventor: OKAMOTO HISAHIRO
IPC: H01L21/78
Filed: 1988-11-08
Abstract: PURPOSE:To prevent an Si piece from sticking on the surface of a semiconductor chip when a die is picked up, by curing an ultraviolet-curing adhesive on the surface of a died chip before the adhesive fixing the died chip is cured so that the adhesive force be weakened. CONSTITUTION:An ultraviolet-curing adhesive 3 made up of acrylic resin or the like is applied on the whole surface of a died chip 21 prepared by cutting and a dieing groove 25. Ultraviolet rays 4 are applied on the whole of the surface of the ultraviolet-curing adhesive 3 so as to cure the same completely. When the curing is completed, the adhesion of the ultraviolet-curing adhesive 3 and the died chip 21 weakens and turns easy to exfoliate, while the adhesion of the ultraviolet-curing adhesive 3 and a sheet material 11 remains strong. Subsequently, ultraviolet rays are applied on the back surface of a died sheet 1 so as to cure the adhesive. Thereby a silicon piece is prevented from sticking on the surface of the died chip when the chip is taken out.
